### RCRA Delisting Technical Support Document Appendix A-1 October 2008 APPENDIX A-1 The following sections provide the methodology and rationale followed for the selection or development of compound-specific parameter values recommended by U.S. EPA OSW. Compound-specific values are provided for (1) physical and chemical properties, (2) fate-and-transport parameters, and (3) health benchmarks. A summary table of all compound-specific parameter values is provided at the end of this appendix, followed by individual parameter-value tables for each compound. The individual parameter-value tables cite sources for each parameter value. A.1.1 COMPOUND NAME with CHEMICAL ABSTRACTS SERVICE (CAS) NUMBER The Appendix A-1 Tables of waste constituents included in the Delisting Risk Assessment Software (DRAS) program are lists the chemicals by most common compound name. The CAS number provided in parenthesis is a unique number assigned to each compound in the table. A.1.2 PHYSICAL AND CHEMICAL PROPERTIES Molecular Weight ( MW ) Molecular weight ( MW ) of a compound is defined as the sum of atomic weights of all atoms in the compound’s molecule. Organics and Metals For most organics (except PCDDs and PCDFs) and metals, MW values were obtained from the following:
C Budavari, S., M.J. O’Neil, A. Smith, and P.E. Heckelman. 1989. The Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals. 11th Edition. Merck and Company, Inc. Rahway, New Jersey. MW values not provided in Budavari, O’Neil, Smith, and Heckelman (1989) were obtained from the following document:
C Montgomery, J.H., and L.M. Welkom. 1991. Groundwater Chemicals Desk Reference. Lewis Publishers. Chelsea, Michigan. Because Budavari, O’Neil, Smith, and Heckelman (1989) provides MW values for most of the compounds evaluated, it was used as the primary source to ensure consistency. MW values are based on the compound’s formula; and, the values in Budavari, O’Neil, Smith, and Heckelman (1989) are the same as the values cited in several literature sources. MW values for most of the compounds in the primary guidance documents were also obtained from Budavari, O’Neil, Smith, and Heckelman (1989). PCDDs and PCDFs MW values for PCDDs and PCDFs were obtained from U.S. EPA (1994a). Mercuric Compounds MW values for mercury and mercuric chloride were obtained from Budavari and others (1989). MW value for methyl mercury was obtained from U.S. EPA (1997g).

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Melting Point Temperature ( T ) m 

### Melting point temperature ( T ) is the temperature of the compound (in degree Kelvin [K]) at which the solid state of the compound undergoes a phase change to a liquid phase. At ambient temperatures and at an atmospheric pressure of 1 atmosphere, compounds are either in a solid or liquid state. m 

### Organics and Metals For most organics (except PCDDs and PCDFs) and metals, values for T were m 

### obtained from Budavari, O’Neil, Smith, and Heckelman (1989). T values not provided in Budavari, O’Neil, Smith, and Heckelman (1989) were obtained from Montgomery and Welkolm (1991). m 

### Because Budavari, O’Neil, Smith, and Heckelman (1989) provides T values for most of the compounds evaluated, it was used as the primary source to ensure consistency. T m 

### values in Budavari, O’Neil, Smith, and Heckelman (1989) were generally within 2 to 3 degrees of the values provided in literature sources reviewed. T m 

### values for most compounds in the primary guidance documents were also obtained from Budavari, O’Neil, Smith, and Heckelman (1989). m


### PCDDs and PCDFs Tmvalues for PCDDs and PCDFs were obtained from U.S. EPA (1994a). U.S. EPA (1994a) provides T values for PCDDs and PCDFs, that were obtained from various literature sources. m 

### Vapor Pressure ( Vp ) and Aqueous Solubility (S ) The vapor pressure ( Vp ) of a substance is defined as the pressure in atmospheres exerted by the vapor (gas) of a compound when it is under equilibrium conditions. It provides a semi-quantitative rate at which it will volatilize from soil and/or water. The aqueous solubility ( S) of a compound is defined as the saturated concentration of the compound in water (mg chemical/L water) at a given temperature and pressure, usually at soil/water temperatures and atmospheric pressure (Montgomery and Welkom 1991). Organics For most organics (except PCDDs and PCDFs), values for Vp and S were obtained from the following:
C U.S. EPA 1994b. Draft Report Chemical Properties for Soil Screening Levels . Prepared for the Office of Emergency and Remedial Response. Washington, DC. July 26. U.S. EPA (1994b) provides measured, calculated, and estimated values for Vp and S that were obtained from various literature sources. Vp values in U.S. EPA (1994b) were generally either measured (at 20 E C to 25 E C) or calculated values obtained from various literature sources. U.S. EPA (1994b), however, E 

### provides values for Vp corrected to 25 C. U.S. EPA (1995a) states that, because the distribution of many of the parameters is skewed, the geometric mean or the median values were preferable to the arithmetic mean values. Therefore, when available geometric mean values were preferred over the arithmetic mean values.

E E 

### In U.S. EPA (1994b), S values were either measured (at 20 C to 30 C) or calculated values obtained from E E 

### various literature sources. Although S values were measured at temperatures ranging from 20 C to 30 C, E 

### U.S. EPA (1994b) states that S values were not corrected to 25 C, because the variability in solubilities E E 

### measured at 20 C to 25 C was within the overall range of measured values. U.S. EPA (1994b) is the preferred source, because (1) sources and the conditions at which each value was obtained are provided, and (2) values were provided to 2 significant figures. Also, U.S. EPA (1994b) A-1-2

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 provides multiple Vpand S values for each compound from several different literature sources; providing a recent, more comprehensive compilation of reported literature values. Vp and S values from U.S. EPA (1994b) were generally consistent with those provided in U.S. EPA (1994e) and U.S. EPA (1995a). When Vp and S values were not available in U.S. EPA (1994b), they were obtained from one of three sources, in the following order of preference: 1. U.S. EPA (1994e) 2. U.S. EPA (1995a); values from which were obtained from one of three sources: a. Mackay, D., W.Y. Shiu, and K.C. Ma. 1992. Illustrated Handbook of Physical-Chemical Properties and Environmental fate for Organic Chemicals. Volume I - Monoaromatic Hydrocarbons, Chlorobenzenes, and PCBs. Volume II-Polynuclear Aromatic Hydrocarbons, Polychlorinated Dioxins and Dibenzofurans. Volume III - Volatile Organic Chemicals. Lewis Publishers. Boca Raton, Florida. b. Howard, P.H. 1989-1993. Handbook of Environmental Fate and Exposure Data For Organic Chemicals . Volumes I: Large Production and Priority Pollutants (1989). Volume II: Solvents (1990). Volume III: Pesticides (1991). Volume IV: Solvents2 (1993) . Lewis Publishers. Chelsea, Michigan. c. Other referenced literature sources, when values were not available in Mackay, Shiu, and Ma (1992) or Howard (1989-1993). 3. U.S. EPA. 1994f. Superfund Chemical Data Matrix (SCDM). Office of Emergency and Remedial Response. Washington, DC. June. Vp and S values in U.S. EPA (1994e) were geometric mean values obtained from various literature sources. References specific to sources of values for each compound were provided in U.S. EPA (1994e) and were, therefore, preferred over U.S. EPA (1995a) values. Most Vp and S values in U.S. EPA (1995a) were obtained from Mackay, Shiu, and Ma (1992) or Howard (1989-1993). Mackay, Shiu, and Ma (1992) and Howard (1989-1993) obtain the “best” values after evaluation of various literature sources. Vp values in U.S. EPA (1994f) were obtained from various literature sources. S values in U.S. EPA (1994f) were the geometric mean of values obtained from various literature sources. Mercuric Compounds Mercury is a relatively volatile compound. Vp and S values for elemental mercury were obtained from Budavari, O’Neil, Smith, and Heckelman (1989). Vp and S values for methyl mercury were not found in the literature.

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Henry’s Law Constant ( H) Henry’s Law constant (H ) is also referred to as the air-water partition coefficient, and is defined as the ratio of the partial pressure of a compound in air to the concentration of the compound in water at a given temperature under equilibrium conditions. Henry’s Law constant values generally can be (1) calculated from the theoretical equation defining the constant, (2) measured, or (3) estimated from the compound structure. Experimental and estimated H values from literature reports, however, are (1) very temperature-dependent and difficult to measure, (2) generally obtained from various literature sources that use different experimental and estimation methods, and (3) available for only a limited number of compounds. Organics For organics (excluding PCDDs and PCDFs), H values were calculated from the following theoretical equation (Lyman, Reehl, and Rosenblast 1982) for consistency, using recommended MW, S, and Vp values:

### H = Henry’s Law constant (atm-m /mole) Vp = Vapor pressure of Chemical (atm) S = Solubility of Chemical in water (mg Chemical/L water) The primary guidance documents also used theoretical Equation A-1-1 to calculate H values. PCDDs and PCDFs H values for PCDDs and PCDFs are calculated values obtained from U.S. EPA (1994a). Metals For all metals (except mercury), H is zero, because Vp—because of the nonvolatile nature of the metals—and S are assumed to be zero. Mercuric Compounds H values for elemental mercury, and methyl mercury were obtained from U.S. EPA (1997g). Diffusivity of Chemicals in Air ( D ) and Water ( D ) a w

### Organics For organics (except PCDDs and PCDFs), diffusivity values were obtained directly from the CHEMDAT8 model chemical properties database (Worksheet DATATWO.WK1):
C U.S. EPA. 1994d. CHEM8—Compound Properties Estimation and Data . Version 1.00. CHEMDAT8 Air Emissions Program. Prepared for Chemicals and Petroleum Branch, OAQPS. Research Triangle Park. North Carolina. November 18. The U.S. EPA (1994c) database uses empirical correlations with compound density and molecular weight to calculate diffusivity values. For compounds not in the U.S. EPA (1994c) database, diffusivity values were obtained by using the WATER8 model correlation equations for air and water diffusivities: A-1-4

### RCRA Delisting Technical Support Document Appendix A-1 October 2008
C U.S. EPA. 1995d. WATER8—Air Emissions Models Wastewater Treatment . Version 4.0. OAQPS. Research Triangle Park. North Carolina. May 1. U.S. EPA (1995c) database values were predicted by using chemical-structural relationships. Diffusivity values for all compounds in the U.S. EPA (1994c) and (1995c) databases were either predicted or estimated. The primary guidance documents also recommended U.S. EPA (1994c) and (1995c) database model values. More recent documents, including the following, also recommended these values:
C U.S. EPA. 1996. Soil Screening Guidance: Technical Background Document and User’s Guide . Office of Solid Waste and Emergency Response. Washington, DC. EPA/540/R-95/128. May. For diffusivity values that were not available in these databases, D and D values were calculated using the following equations cited and recommended for use in U.S. EPA (1997g): w a 

## Equation A1-2a Equation A1-2b U.S. EPA (1995a) recommended the use of standard default diffusivity values. U.S. EPA (1995a) stated that the diffusivity parameters vary slightly, and default values appear to be within the range of typical 2 

### values. Values for diffusivity in air range from about 0.01 to 0.1 square centimeters per second (cm /s); 2 

### therefore, U.S. EPA (1995a) recommended a default value of 0.08 cm /s. Values for diffusivity in water -06 -05 2 

### range from 1 x 10 to 1 x 10 cm /s; therefore, U.S. EPA (1995a) recommended a default value of -06 2 

### 8 x 10 cm /s. Diffusivity values calculated using Equations A-1-2a and A-1-2b were within the range specified by U.S. EPA (1995a). PCDDs and PCDFs Diffusivity values in air and water for (1) 2,3,7,8-TCDD were obtained from U.S. EPA (1994c). Metals and Mercuric compounds For metals (except chromium and mercury), diffusivity values were not available in the literature. Diffusivity values for chromium and mercury were obtained from the U.S. EPA (1994c) database. The diffusivity value for methyl mercury was calculated using Equations A-1-2a and A-1-2b.

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Soil Organic Carbon-Water Partition Coefficient ( K )

oc 

### The soil organic carbon-water partition coefficient (K ) or the organic carbon normalized soil sorption coefficient is defined as the ratio of adsorbed compound per unit weight of organic carbon to the aqueous solute concentration (Montgomery and Welkom 1991). oc 

### Organics Because of the soil mechanisms that are inherently involved, K values for the ionizing organics and nonionizing organics are discussed separately. oc 

### Ionizing Organic Compounds Ionizing organic compounds include amines, carboxylic acids, and phenols. These compounds contain the functional groups that ionize under specific pH conditions, and include the following:

oc 

### C Organic acids (2,4,6-trichlorophenol; pentachlorophenol; 2,3,4,5-tetrachlorophenol; 2,3,4,6-tetrachlorophenol; 2,4,5-trichlorophenol; 2,4-dichlorophenol; 2-chlorophenol; phenol; 2,4-dimethylphenol; 2-methylphenol; 2,4-dinitrophenol; and benzoic acid)
C Organic bases—n-nitroso-di-n-propylamine; n-nitrosodiphenylamine, and 4-chloroaniline) K v alues for ionizing organic compounds were obtained from U.S. EPA (1994b). U.S. EPA (1994b) provides K values for the ionizing organic compounds that have been estimated on the basis of the degree of ionization and the relative proportions of neutral and ionized species. The primary guidance documents cite one value for the ionizing organics, independent of the pH. The primary guidance documents calculate oc 

### K values for the ionizing organics by using correlation equations containing K that are applicable to

oc ow 

### nonionizing organics. However, K values for ionizing compounds can vary vastly, depending on the pH oc 

### conditions in the environment. For the ionizing organic compounds, the estimated K values based on pH are provided. oc 

### K values were estimated on the basis of the assumption that the sorption of ionizing organic compounds is similar to hydrophobic organic sorption, because the soil organic carbon is the dominant sorbent. According to U.S. EPA (1994b), for low pH conditions, these estimated values may over predict sorption coefficients, because they ignore sorption to components other than organic carbon.

oc 

### Nonionizing Organic Compounds Nonionizing organic compounds are all other organic compounds not listed earlier as ionizing. They include volatile organics, chlorinated pesticides, polynuclear aromatic hydrocarbons (PAHs), and phthalates. The geometric mean of measured K values are provided in the following document: oc

### Chemical Partitioning, Partitioning Coefficients for Soil-Water ( Kd ) and Suspended s 

### Sediment-Surface Water ( Kd ) sw 

### Partition coefficients ( Kd) describe the partitioning of a compound between sorbing material, such as soil, soil pore-water, surface water, suspended solids, and bed sediments. For organic compounds, Kd has been estimated to be a function of the organic-carbon partition coefficient and the fraction of organic carbon in the partitioning media. For metals, Kd is assumed to be independent of the organic carbon in the partitioning media and, therefore, partitioning is similar in all sorbing media. The soil-water partition coefficient (Kd ) describes the partitioning of a compound between soil pore-water and soil particles, and strongly influences the release and movement of a compound into the subsurface s 

### soils and underlying aquifer. The suspended sediment-surface water partition coefficient ( Kd ) coefficient describes the partitioning of a compound between surface water and suspended solids or sediments. sw 

### Organics For organics (including PCDDs and PCDFs), soil organic carbon is assumed to be the dominant sorbing component in soils and sediments. Therefore, Kd values were calculated using the following fraction organic carbon ( f

OC 

### ) correlation equations: 

## Equation A-1-3a Equation A-1-3b U.S. EPA. 1993. Review Draft Addendum to the Methodology for Assessing Health Risks Associated with Indirect Exposure to Combustor Emissions . Office of Health and Environmental Assessment. Office of Research and Development. EPA-600-AP-93-003. November 10. U.S. EPA (1993d), from literature searches, states that f OC

### could range as follows:
C 0.002 to 0.024 in soils—for which a mid-range value of f oc,s 

### = 0.01 generally can be used. C 0.05 to 0.1 in suspended sediments—for which a mid-range value of f = 0.075 generally can be used. oc,sw 

### The DRAS uses mid-range f values recommended by U.S. EPA (1993). Kd values were calculated using oc 

### K values recommended for each compound.

oc 

### Metals For metals (except mercury), Kd is governed by factors other than organic carbon, such as pH, redox, iron content, cation exchange capacity, and ion-chemistry. Therefore, Kd values for metals cannot be calculated using the same correlation equations specified for organic compounds. Instead, Kd values for the metals must be obtained directly from literature sources. Kd values for all metals, except lead, were obtained from U.S. EPA (1996a). U.S. EPA (1996a) provides values for Kd that are based on pH, and are estimated by using the MINTEQ2 model, which is a geochemical speciation model. The MINTEQ2 model analyses were conducted under a variety of geochemical conditions and metal concentrations. The A-1-8

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 MINTEQ2 pH-dependent Kd values were estimated by holding constant the iron oxide at a medium value and the f at 0.002. For arsenic, hexavalent chromium, selenium, and thallium, empirical pH-dependent Kd values were used. oc 

### Kd value for lead was obtained from the following:
C Baes, C.F., R.D. Sharp, A.L. Sjoreen, and R.W. Shor. 1984. “Review and Analysis of Parameters and Assessing Transport of Environmentally Released Radionuclides Through Agriculture.” Oak Ridge National Laboratory, Oak Ridge, Tennessee. Mercuric Compounds Both watershed erosion and direct atmospheric deposition can be important sources of mercury to a water body (U.S. EPA 1997g). There appears to be a great deal of variability in the processing of mercury among water bodies. This variability is primarily a result of the characteristically wide range of chemical and physical properties of water bodies that influence the levels of methylated mercury. Some of the mercury entering the water body is methylated predominately through biotic processes (U.S. EPA 1997g). In the absence of modeling site-specific water body properties and biotic conditions, consistent with U.S. EPA (1997g), U.S. EPA OSW recommends 85 percent of total mercury in surface water is assumed to be divalent mercury and the remaining mass as methyl mercury. For the fish ingestion pathway, the DRAS converts the total mercury in the surface water to the methyl mercury fraction by multiplying the total mercury concentration in a second order stream by 0.15 to determine the methyl mercury concentration. Kd values for mercury and methyl mercury were obtained from U.S. EPA (1996a) . The Kd value for methyl mercury was obtained from U.S. EPA (1997g). s 

### Aquatic Toxicity Reference Values ( Aquatic TRVs ) Ecological benchmarks were developed for the protection of the aquatic community. These ecological benchmarks are referred to as toxicity reference values (TRVs) and were developed from a variety of ecological receptors based on the availability of data for a given waste constituent. The TRV is developed to protect the entire community, not one particular species. In general, TRVs (the measurement endpoints) were selected for consistency with the Agency's “Framework for Ecological Risk Assessment” (U.S. EPA 1992b). Region 6 believes the ecological analysis is conservative with respect to the overall assessment endpoint (e.g., sustainability of the reproducing populations) because of the way the source, fate and transport parameters are set and how the TRVs are developed. The ecological assessment focused on inferring the sustainability of populations and communities within the aquatic ecosystem. Therefore, TRVs were derived from measurement endpoints (i.e., reproductive, developmental, growth, survival, and mortality) from which such inferences could be made. Reproductive studies (e.g., number of viable young per female) were preferred over other endpoints. The aquatic TRVs defaulted to a more conservative no effects level (or concentration) approach for ecological receptors. For populations of fish and aquatic invertebrates (represented by daphnids), a hierarchical approach was taken for use of data sources in deriving aquatic TRVs. The first choice was the final chronic values (FCVs) from the Ambient Water Quality Criteria (AWQC) effort by the EPA Office of Water (U.S. EPA 1998a). If these benchmarks were not available, then a freshwater aquatic TRV was selected from the draft Protocol for Screening Level Ecological Risk Assessment at Hazardous Waste Combustion Facilities (U.S. EPA. 1998b). Finally, TRVs were selected from the Toxicological Benchmarks for Screening Potential contaminants of Concern for Effects on Aquatic Biota(Suter and Tsao, 1996).

### ) and for all metals, except lead and mercury, as cited in U.S. EPA (1995a). This implies that the concentration of chemical in the fish is only due to water intake by the fish, and compounds with a log K ow

BCF values reported in the DTSD Appendix are either: 1) Geometric mean of a valid number of field-measured values obtained from various field studies (or) 2) Geometric mean of laboratory-measured values obtained from various experimental studies (or) 3) Estimated values calculated using a correlation equation NOTE :	 When only one valid field-measured value for a chemical was found in the literature, the higher of the field-measured value and the geometric mean of laboratory-measured values, was used. In general, field measured BCFs were assumed to be based on total (dissolved and suspended) water column concentrations; and laboratory measured BCFs were assumed to be based on dissolved water column concentrations. This distinction is important for compounds with a log K of greater than or equal to 4.0, because significant amounts of a chemical can partition into the suspended sediment organic carbon ow

This information is summarized in the following document: U.S. EPA. 1998b. Screening Level Ecological Risk Assessment Protocol for Hazardous Waste Combustion Facilities. Draft Interim Final. April . Field-measured data is only (1) available for a limited number of compounds, and (2) based on a single study. In such cases, the field-measured value or the geometric mean of field-measured values were compared with the geometric mean of laboratory-measured values, and the higher one used. A detailed discussion on sources of BCF values and methodology followed are provided in Appendix C of U.S. EPA (1998b).
C When measured values were not available or could not be evaluated, the following correlation equation recommended by Lyman, Reehl, and Rosenblatt (1982) was used: 

## Equation A-1-4 Correlation Equation A-1-4 was developed by the following:

For compounds with a log K of greater than or equal to 4.0, chemicals can significantly partition into the suspended sediment organic carbon (or particulate phase) of the water column. Therefore, BAF values should be based on total (dissolved and suspended) water column concentrations. BAFs reported are either: ow

BCFs were estimated using correlation Equation A-1-4. NOTE :	 When only one valid field-measured value for a chemical was found in the literature, the higher of the field-measured value and the geometric mean of laboratory-measured values, was used. In general, (1) field-measured BAFs were assumed to be based on total (dissolved and suspended) water column concentrations, (2) laboratory-measured BCFs, and therefore, the BAFs predicted from them, were assumed to be based on dissolved water column concentrations, and (3) estimated BCFs using correlation Equation A-1-4, and therefore, the BAFs predicted from them, were assumed to be based on dissolved water column concentrations. In addition, field-measured BCFs, for compounds with a log K greater than 4.0, were assumed to be equal to BAFs, because the tissue concentrations are a result of uptake of water (dissolved and suspended), sediment, and various trophic level food. ow 

### For consistency, all field-measured BAF (or BCF) values were adjusted according to the methodology specified in U.S. EPA (1995e) to include only the dissolved water column fractions; (i.e., the BAFs based on total water concentrations were converted to BAFs based on dissolved water concentrations). This was done, so that all BAF fish 

### values (based on dissolved water concentrations) can be multiplied by the chemical concentration in the dissolved water column ( C dw 

### ) to calculate fish concentrations. In U.S. EPA (1995a), BAF values were estimated based on the models developed for the limnetic ecosystem by the following:
C Thomann, R.V. 1989. “Bioaccumulation Model of Organic Chemical Distribution in Aquatic Food Chains.” Environmental Science and Technology . 23(6):699-707. and, for the littoral ecosystem by the following:

Parkerton. 1992. “An Equilibrium Model of Organic Chemical Accumulation in Aquatic Food Webs with Sediment Interaction.” Environmental Toxicology and Chemistry. 11:615-629. BAF values were predicted by multiplying a laboratory-measured or predicted BCF by a FCM. The Thomann (1989) and Thomann, Connolly, and Parkerton (1992) models were adopted by U.S. EPA, Office of Water, for the Great Lakes Water Quality Initiative in 1993. In 1995, U.S. EPA, Office of Water, developed BAFs based on the following study: A-1-12

C Gobas, F.A.P.C. 1993. “A Model for predicting the bioaccumulation of hydrophobic organic chemicals in aquatic food-webs: application to Lake Ontario.” Ecological Modelling. 69:1-17. The Gobas (1993) model was adopted to develop the latest water quality criteria and is provided in the following two documents:
C U.S. EPA. 1995d. Water Quality Guidance for the Great Lakes System. Supplementary Information Document. Office of Water. EPA-820-B-95-001. March.
C U.S. EPA. 1995e. Great Lakes Water Quality Initiative. Technical Support Document for the Procedure to Determine Bioaccumulation Factors . Office of Water. EPA-820-B-95-005. March. The Gobas (1993) food-chain model was preferred because, unlike the Thomann (1989) model, it includes both benthic and pelagic food chains, thereby estimating exposure of organisms to compounds from both the sediment and the water column. Other inherent drawbacks of the Thomann (1989) model were that the model: (1) did not take into account metabolism, biotransformation, degradation, persistence, or seasonal or temporal variability, (2) is extremely sensitive to certain input parameter such as the lipid content, (3) incorrectly adopted FCMs, (4) is questionable in its assumption that the system is at steady state or in equilibrium, and (5) had little application for compounds with a log K greater than 6.5, because the sediment route of exposure was not considered. ow 

### The Gobas (1993) model: (1) accounts for metabolism, but sets the metabolic rate to zero because of lack of data for individual compounds, (i.e., the metabolism is assumed not to occur), (2) incorporates the concentration of the compound in both the sediment and the water column, the sediment route being especially useful for compounds with a log K greater than 6.5, and (3) includes the disequilibrium between concentrations of the compounds in sediment and the water column. Although the Thomann, Connolly, and Parkerton (1992) model accounts for sediment interaction, according to U.S. EPA (1995d), the Gobas (1993) model required fewer input parameters which could be more easily specified. ow 

### The following equation cited in U.S. EPA (1995e) was used to convert the BAF based on total water concentrations to a BAF based on dissolved water concentrations: 

## Equation A-1-5 where f fd 

### = fraction of chemical that is freely dissolved in water DOC = concentration of dissolved organic carbon, kg organic carbon / L water POC = concentration of particulate organic carbon, kg organic carbon / L water Since, the Gobas (1993) model was derived from a study conducted at Lake Ontario, DOC and POC values for Lake Ontario were used.

## Equation A-1-6 FCMs were obtained from Table 2 of U.S. EPA (1995e). U.S. EPA (1995e) provided FCMs as a function of log K in increments of 0.1 for trophic level 2, 3, and 4 aquatic organisms. Humans are assumed to consume trophic level 3 or 4 fish. The higher FCM value of trophic levels 3 and 4 was used. When the ow

FCMs were obtained from U.S. EPA (1995e). Metals (lead) For lead, the food-chain multiplier becomes greater than 1; therefore, a BAF is more appropriate. The BAF fish

A.1.4 HUMAN HEALTH BENCHMARKS DRAS incorporates human health benchmarks as reference doses and reference concentrations for noncarcinogens, and as cancer slope factors for carcinogens. Reference dose (RfD ) is defined as a daily intake rate of a compound estimated to pose no appreciable risk of deleterious effects over a specific exposure duration (U.S. EPA 1989). Reference concentration ( RfC) is defined as the concentration of a compound estimated (with uncertainty spanning perhaps an order of magnitude) to pose no appreciable risk A-1-14

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 of deleterious effects over a specific exposure duration (U.S. EPA 1989). EPA defines cancer slope factors as “ used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit, on the increased cancer risk from a lifetime exposure to an agent by ingestion [or inhalation]”. Updated Toxicity Data EPA reviewed all existing toxicity reference data in DRAS for outdated or errant values. To do so, EPA downloaded the 2004 version of the Region 9 Preliminary Remediation Goals (PRGs)(U.S. EPA 2004a) toxicity reference values to those in DRAS. We also reviewed Agency sources for any other changes which may have occurred after the 2004 PRG table was prepared. Some of the updates were straightforward such as an unambiguous revision to the Integrated Risk Information System (IRIS – EPA’s highest standard source for toxicity data). Other discrepancies required the review of Agency toxicologists in determining the appropriate default data for use in DRAS. In consideration of the exposure scenarios evaluated in the delisting program, EPA selected toxicity data in accordance with the hierarchy described in the December 2003 Memorandum from Michael B. Cook (U.S. EPA 2003), as did Region 9 in developing the 2004 PRG list. The types of pathway evaluations are very similar to those applied for Superfund-site evaluations. The hierarchy recommended is as follows: IRIS is the first tier of the recommended hierarchy as the generally preferred source of human health toxicity values. IRIS generally contains reference doses (RfDs),reference concentrations (RfCs), cancer slope factors, drinking water unit risk values, and inhalation unit risk values that have gone through a peer review and EPA consensus review process. IRIS normally represents the official Agency scientific position regarding the toxicity of the chemicals based on the data available at the time of the review. The second tier is EPA’s [Provisional Peer Reviewed Toxicity Values] PPRTVs. Generally, PPRTVs are derived for one of two reasons. First, the [Superfund Health Risk Technical Support Center] STSC is conducting a batch wise review of the toxicity values in [the EPA Health Effects Summary Tables] HEAST (now a Tier 3 source). As such reviews are completed, those toxicity values will be removed from HEAST, and any new toxicity value developed in such a review will be a PPRTV and placed in the PPRTV database. Second, Regional Superfund Offices may request a PPRTV for contaminants lacking a relevant IRIS value. The STSC uses the same methodologies to derive PPRTVs for both. The third tier includes other sources of information. Priority should be given to sources that provide toxicity information based on similar methods and procedures as those used for Tier I and Tier II, contain values which are peer reviewed, are available to the public, and are transparent about the methods and processes used to develop the values. Consultation with the STSC or headquarters program office is recommended regarding the use of the Tier 3 values for Superfund response decisions when the contaminant appears to be a risk driver for the site. In general, draft toxicity assessments are not appropriate for use until they have been through peer review, the peer review comments have been addressed in a revised draft, and the revised draft is publicly available. In October 2008, IRIS and PPRTV were checked once more for updates and added to DRAS in accordance with the Cook Memorandum. A-1-15

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Explanation of Calculated Toxicity Benchmark Values – Route-to-Route Extrapolation To calculate missing benchmarks, available benchmarks can be employed using a methodology referred to as route-to-route extrapolation . Route-to-route extrapolation is when a toxicity factor for one route of exposure (i.e. ingestion) is converted into a toxicity factor for another route of exposure (i.e. inhalation). DRAS includes route-to-route extrapolations from the R9 2004 PRGs based on criteria set forth in “Methods for Derivation of Inhalation Reference Concentrations and Application of Inhalation Dosimetry” (U.S. EPA 1994g). Specifically, EPA believed that the most appropriate way to evaluate a large group of chemicals for route-to-route extrapolations was by applying the following criteria from the 1994 report: Oral data should not be used for route-to-route extrapolation in the following instances: (1) when groups of chemicals are expected to have different toxicity by the two routes; for example, metals, irritants, and sensitizers; . . . (6) when short-term inhalation studies, dermal irritation, in vitro-studies, or characteristics of the chemical indicate potential for portal-of-entry effects at the respiratory tract, but studies themselves are not adequate for an RfC development. The following databases were used for the evaluation: (a) EPA’s database for chemicals determined to be extremely hazardous substances after release to ambient air. These include chemicals assigned an EPA Level of Concern (LOC) as found in the document: “Technical Guidance for Hazards Analysis: Emergency Planning for Extremely Hazardous Substances” (U.S. EPA 1987); (b) Emergency Planning Response Guideline (ERPG) values for protection of the general public from the acute toxic and/or debilitating effects of chemicals in ambient air. ERPGs are developed by the American Industrial Hygiene Association ( http://www.orau.gov/emi/scapa/erpgdefinitions.htm) (AIHA 2005); (c) U.S. DOE Temporary Emergency Exposure Limit (TEEL) values for protection of Federal workers and contractors at DOE facilities from the acute toxic and/or debilitating effects of chemicals in ambient air. TEELs are developed by methodologies similar to the ERPGs but include more chemicals ( http://www.orau.gov/emi/scapa/teels.htm ) (U.S. DOE 2005) ; and (d) NIOSH Recommended Exposure Limit (REL) values for work place exposure. This encompasses chemicals that have been assigned a specific time-concentration exposure limit in ambient air because they are documented to be respiratory irritants (even for a healthy worker) in ambient air in the absence of exposure protection. ( www.cdc.gov/niosh/92-100.html ) (U.S. DHHS 1992). DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (a) include: Acrylamide; Aldrin; Benzyl Chloride; o-Cresol; Endosulfan; Endrin; Disulfoton; Furan; N-Nitrosodimethylamine; Parathion; Pentachlorophenol; Phenylmercuric acetate; Phorate; DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (b) include:

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Allyl chloride; Benzyl Chloride; Carbon tetrachloride; Methanol; Phenol; Trichloroethane (-1,1,1 and -1,1,2); Hexachlorobutadiene DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (c) include: Acrylamide; allyl chloride; aniline; benzo[a]pyrene; 2,4-dinitrophenol; dibenzo[a,h]anthracene; strychnine; hexachloroethane; hexachlorophene; chloromethane; tribromomethane; methanol; heptachlor; 1,2-dichloropropane; 1,1,2-trichloroethane; 1,1,2,2-tetrachloroethane; 1,1,1,2-tetrachloroethane; pentachloronitrobenzene; diethylphthalate; dibutylphthalate; pentachlorophenol; 2-chloronaphthalene; 3,3Æ-dichlorobenzidene; o-cresol; p-cresol; m-cresol; o-toluidene; 2-chlorophenol; 1,2,4,5-tetrachlorobenzene; 2,4,5-trichlorophenol; 1,3,5-trinitrobenzene; 1,3-dinitrobenzene; p-chloroaniline; pyridine; hexachlorobenzene; hexachlorobutadiene; 3,3-dimethoxybenzidine; 2,4-dichlorophenol; pentachlorobenzene; DDE; DRAS chemicals for which Region 9 recommends a route-to-route extrapolation also found in (d) include: Acetone - nose and throat irritant Acetonitrile - nose and throat irritant Bromoform - respiratory irritant Dichlorobenzenes (all isomers) - upper respiratory irritants Dichloroethylenes (all isomers) - mucous membrane irritants; narcosis; Dimethylphthalate - upper respiratory irritant Ethyl acetate - respiratory and eye irritant Methyl acetate - upper respiratory irritant Pentachlorophenol - upper respiratory irritant Phenylenediamine - bronchial irritant and asthma inducer Strychnine - convulsions Trichloropropane - mucous membrane irritant; narcosis; Consequently, for the above chemical constituents, we recommended against using route-to-route extrapolation from oral route data to derive inhalation toxicity factors. For the remainder of the chemicals in the R9 2004 PRGs where extrapolation is used, the use of the route-to-route extrapolation in DRAS could be adopted on the basis that direct exposure effects of the remaining chemicals on the lung or respiratory system (of humans or animals) could not be identified. However, there could still be some significant uncertainties in the reliability of inhalation toxicity factors derived in this way. The primary uncertainty would probably be due to the rate of metabolism of a given chemical in the liver or lung and how that factor affects the ultimate level of absorption and transport to target organs. In the event that one of these route-to-route values becomes the basis for potentially denying a delisting petition, Region 5 recommends that the reference value be further investigated to reduce this uncertainty. In order to carry on the evaluation further, published literature studies on the metabolism or pharmacology of the individual chemicals would need to be located and reviewed. The discussion above covers the concept of using route-to-route extrapolation from oral route data to derive inhalation toxicity factors. In the R9 2004 PRGs, there are also some instances where DRAS lists oral toxicity factors that were apparently derived from IRIS verified inhalation toxicity factors. The use of this extrapolation procedure would also be subject to uncertainty. For the purposes of making an expedited screening level evaluation, we propose the following caveat: the route-to-route extrapolation from A-1-17

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 inhalation to oral should only be used when there is well documented evidence that exposure via the inhalation route results in adverse effects at organs or organ systems that are distant from the lung and respiratory tract (e.g., liver, kidney, thyroid, sex organs). The evaluation based on applying the above caveat is shown below: RfD O 

### for Acetonitrile: IRIS reports health effects distant from the lung, therefore the route-to-route extrapolation is satisfactory. RfD O 

### for Benzyl chloride: R9 lists an RfC referenced to NCEA. We recommend not using the route-to-route extrapolation until we are able to verify the health effects reported in this reference. RfD O 

### for Chlorodifluoromethane: IRIS reports health effects distant from the lung, therefore the route-to-route extrapolation is satisfactory. RfD O 

### for Chloromethane: Because IRIS states that exposure to chloromethane can essentially occur only through the vapor phase, derivation of an oral toxicity factor is not necessary. RfD O 

### for 3-Chloropropene (Allyl chloride): IRIS reports peripheral neurological effects in humans and liver and kidney degenerative effects in lab animals; under the assumption that oral exposure to Allyl Chloride could occur, the route-to-route extrapolation is satisfactory; RfD O 

### for 1,2-Dichloropropane: IRIS reports that the observed adverse effects were seen only in the nasal tissue and respiratory epithelium; therefore, route-to-route extrapolation should not be used; RfD O 

### for 2-Nitropropane: IRIS reports development of focal hepatocellular nodules and focal liver necrosis in lab animals with no significant effects on the respiratory tract; under the assumption that oral exposure could occur to Nitropropane, the route-to-route extrapolation is satisfactory. Provisional Toxicity Data, Multiple CAS ID Numbers, Multiple Valence States, and Data Based on a Mixture of Compounds Approximately 26 potential waste constituents have provisional toxicity data, multiple CAS identification numbers, valence states, or toxicity data based on a mixture of compounds.

For purposes of evaluating arsenic risk, EPA generally evaluates arsenic risk as Total arsenic unless a specific regulation spells out how arsenic should be analyzed and reported. If the DRAS program directs petitioners to report results for Ar(III) and Ar (V), there is still only one set of toxicity factors available. 4) We didn’t need to use CalEPA values.

### 2) An RfC value of 0.0007 (mg/m )is found in IRIS and we used this value to calculate RfD of 0.0002 (mg/kg-day). We replaced the existing value with the new calculation. I 

### 3) IRIS states that the toxicology studies used to derive the toxicity factors were performed by administering Technical grade Chlordane to animals for both the oral and inhalation exposure routes. IRIS gives a definition of Technical grade Chlordane. Therefore, if the petitioner performs an analysis for Technical grade Chlordane or some other form of Chlordane, there is only one set of toxicity factors. Chloroethane (Ethyl Chloride) 3 

### 1) An RfC value of 10 (mg/m )is found in IRIS and we used this value to calculate RfD of 2.86 (mg/kg-day). We replaced the existing value with the new calculation. I 

### 2) The other listed DRAS toxicity values are correct. 3) The oral cancer slope factor could not be verified and a superseded document from NCEA did not match with R9's estimates of the inhalation slope factor, therefore we do not recommend that the carcinogenic toxicity factors be left blank at this time. Chloroform 1) When the IRIS file for chloroform was revised (Oct. 2001), EPA made a significant change in its interpretation of the toxicological evidence. In particular, IRIS determined that ingested chloroform acts by non-linear Mode of Action – chloroform must induce cytotoxicity as a prerequisite for the induction of tumors in rodents. In addition, at dose levels below the oral RfD, chloroform does not induce the level of cytotoxicity and regenerative hyperplasia needed to induce the tumorigenic response. Therefore, the RfD was determined to be an adequate dose benchmark for cancer prevention. The following is the explanation found in the IRIS file: In the case of chloroform, the mode of action of carcinogenicity is reasonably well understood. Available data indicate that chloroform is not strongly mutagenic and chloroform is not expected to produce rodent tumors via a mutagenic mode of action (ILSI, 1997). Rather, there is good evidence that carcinogenic responses observed in animals are associated with regenerative hyperplasia that occurs in response to cytolethality (ILSI, 1997; U.S. EPA, 1998a,b). Because cytolethality occurs only at exposure levels above some critical dose level, a nonlinear approach is considered the most appropriate method for characterizing the cancer risk from chloroform. A-1-20

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 The Proposed Guidelines for Carcinogenic Risk Assessment (U.S. EPA, 1996) state that when the mode-of-action analysis based on available data indicates that the carcinogenic response is secondary to another toxicity that has a threshold, the margin-of-exposure analysis performed for toxicity is the same as is done for a noncancer endpoint, and an RfD for that toxicity may be considered in the cancer assessment. For chloroform, available evidence indicates that chloroform-induced carcinogenicity is secondary to cytotoxicity and regenerative hyperplasia; hence, the Agency relies on a nonlinear dose-response approach and the use of a margin-of-exposure analysis for cancer risk. The Agency has also chosen not to rely on a mathematical model to estimate a point of departure for cancer risk estimate, because the mode of action indicates that cytotoxicity is the critical effect and the reference dose value is considered protective for this effect. For more discussion of margin of exposure (MOE), see the Toxicological Review for Chloroform. Based on the kidney tumor of the drinking water study (Jorgenson et al., 1985), a point of departure (Pdp or LED10) of 23 mg/kg/day can be calculated using quantitative modeling of tumor dose-response data. Comparing the Pdp to the RfD of 0.01 mg/kg/day leads to a MOE of 2,000, which is considered large. Thus, in this case, the RfD for noncancer effect is also considered adequately protective of public health for cancer effects by the oral route, on the basis of the nonlinear dose response for chloroform and the mode of action for both cancer and noncancer effects having a common link through cytotoxicity. We concluded that the existing CSF O

### . I 

### 3) The listed DRAS RfD O 

### value from IRIS is acceptable to use. 4) The 2004 Region 9 PRG referenced a value from NCEA for the RfC, 0.049 mg/m . 3 

### We could not locate this reference. The latest Region 9 PRG (2008) lists a value derived from ATSDR. An RfC of 9.93E-02 (mg/kg day) was derived from a chronic inhalation minimum risk level (MRL) published by ATSDR in 1997. Chromium 1) For Cr(III), IRIS states that the following factors cannot be developed: RfC (RfD ), CSF , and IUR I O 

### (CSF ); therefore deleted those values from DRAS; for Cr(III), DRAS lists only an RfD of 1.5 (mg/kg-day). I O 

### 2) For Cr (VI), the listed DRAS RfD O 

### is correct; 3 I I 

### 3) Since the IRIS RfC is 8E-06 (mg/m ) the DRAS RfD should be 2.3E-06 (mg/kg-day). This RfD is for Cr(VI) mists and aerosols (e.g., chromium plating operations). If the potential exposure is more likely to 3 

### be from Cr(VI) particulates, IRIS suggests that an RfC of 1E-04 (mg/m ) should be used, and the corresponding RfD is 2.9E-05 (mg/kg-day). I 3 -1 -1 I 

### 4) For Cr (VI), the IRIS IUR is 1.2E-02 (ug/m ) and the calculated CSF is 42 (mg/kg-day) . As stated in IRIS, industrial worker exposure was known to be from Cr(VI)-Cr(III) mixtures, so there is some A-1-21

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 uncertainty in the actual slope factor that would be due to Cr(VI) alone. The Cr(VI):Cr(III) ratio was assumed to be at least 1:6 for development of the slope factor; therefore, the highest possible CSF would be 7 x 42 = 294 (mg/kg-day) -1 

### . Therefore, we used this latter value if exposure needs to be modeled as due to Cr(VI) alone; if the suspected exposure would be due to a mixture of valences, we suggest using the 42 (mg/kg-day) -1

### 1) The listed HEAST RfC value of 0.5 (mg/m ) is correct and is the only provisional toxicity factor available until the IRIS file is revised. Therefore, the calculated RfD value should be 0.143 (mg/kg-day) in DRAS; I

### is acceptable based on the same rationale used above for Benzo(k)fluoranthene. I 

### Lead There are no IRIS cancer slope factors or Reference Doses for lead. EPA bases the protective media concentration on an uptake-absorption model in children up to seven years old in the child model; and for a pregnant woman in the adult model (to provide protection to the adult and the unborn child). The general cleanup program policies are: lead releases to residential soil should not cause total soil lead concentration to exceed 400 (mg/kg); lead releases to industrial/commercial use soil (i.e., adult only exposure) should not cause total soil concentration to exceed 800 (mg/kg); Mercury 1) The CASRN of 7439-97-6 means Hg(0) or elemental mercury. The listed DRAS RfD value and RfC value are correct however, there is no RfD O 

### value for Hg(0), so it is not appropriate to use the value from methyl mercury. I 

### 2) Mercury and compounds: This for the inorganic Hg valence states above zero, including Hg(II), such as HgCl2 and HgO. The only available toxicity factor is the RfD O 

### of 0.0003 (mg/kg-day). 3) Methyl mercury: This is for organic mercury that has accumulated and bioconcentrated in organic tissues (e.g., fish, wildlife). The only available toxicity factor is the RfD O 

### of 0.0001 (mg/kg-day). This constituent is not easy to measure accurately in tissues. So the default assumption is that all mercury detectable in organic tissues is methyl mercury; 4) DRAS currently includes separate constituents of concern for mercury and methyl mercury due to the differences in both toxicity and fate and transport in the environment. Methyl mercury is listed as Mercury (Fish Pathway Only) while all other forms of mercury are evaluated under Mercury. Naphthalene 3 O I

### . Nickel 1) The CASRN of 7440-02-0 is for nickel salts or nickel compounds. The listed DRAS RfD O 

### of 0.02 (mg/kg-day) should be used for ingestion of all forms of nickel except nickel subsulfide as explained below. I -1

### for inhalation of all forms of nickel except nickel 2) Use the listed R9 CSF of 0.84 (mg/kg-day) subsulfide as explained below. We did not assume route-to-route extrapolation to derive a CSF O 

### value. 3) If nickel subsulfide needs to be retained as a DRAS constituent because of a specific industrial process, we can use the listed R9 CSF value of 1.7 (mg/kg-day) -1

### as the DRAS value for CSF . We did not assume route-to-route extrapolation to derive a CSF O 

### value. I I 

### Polychlorinated biphenyls (PCBs) (Aroclors) In most PCB analyses performed by the historical EPA method, the results are presented as an amount of total Aroclors and/or amounts of specific Aroclors (1254, 1260, 1248, etc.). This gives very little information about the actual level of chlorination in the mixture. So when Aroclor analysis is performed, assume that the mixture is highly chlorinated and use the “high risk” slope factors: CSF O 

### = 2 -1 -1 

### (mg/kg-day) ; and CSF I 

### = 2 (mg/kg-day) . For non-cancer hazard, assume that the mixture is composed of the most hazardous Aroclor (1254) and use the RfD O 

### = 0.00002 (mg/kg-day). In this case, it is acceptable to use route-to-route extrapolation and apply an RfD value of 0.00002 (mg/kg-day) because of evidence that inhalation exposure of PCBs can result in adverse effects at distant sites from the lung. I 

### To apply the “low risk” toxicity factors, the petitioner needs to perform a more refined sample analysis. For example, to obtain evidence for a low risk mixture, GC-MS analysis needs to be performed to accomplish an isomer group analysis that will report the results as mono- through deca- PCB homologs. This will yield more specific data about the chlorine content of the mixture. Then IRIS states that the mixture should be assumed to be low risk only if “congener or isomer analyses verify that congeners with more than 4 chlorines comprise < 0.5% of the total PCBs.” And by analogy, only apply the highest RfD O 

### of 0.00007 (mg/kg-day) if analysis shows that the chlorine content is very low or if the mixture can be verified to be composed of only Aroclor 1016. TCDD, 2,3,7,8 The listed DRAS CSF and CSF are correct. The only available source of toxicity factors is HEAST until the EPA finalizes the Dioxin Reassessment. O I

### RCRA Delisting Technical Support Document Appendix A-1 October 2008 Tetrachloroethylene (PCE) The CalEPA values are acceptable as the most recent data from an approved tertiary source of reference data according to the Cook memo. The CalEPA provisional toxicity factors are: CSF O

### = 0.021 (mg/kg-day) (based on an IUR of 5.9E-06 (ug/m ) ; and 3 

### Chronic Inhalation REL = 35 (mg/m ). 3 3 I 

### Thus, the RfC = 0.035 (mg/m ), RfD is 0.035 times 20 (m /day) divided by 70 kg = 0.01 (mg/kg-day). The listed IRIS RfD O 

### is 0.01 (mg/kg-day). In this case, it is acceptable to apply route-to-route extrapolation since studies of inhalation exposure in mice showed that exposure by this route resulted in liver toxicity and liver tumors. Then the RfD is 0.01 (mg/kg-day). I 

### Trichloroethylene (TCE) There is a recent EPA risk assessment which received external peer review (Trichloroethylene Health Risk Assessment: Synthesis and Characterization; ORD 2001). This document recommended some toxicity factors, in particular, a new cancer slope factor. However, EPA decided not to move ahead and finalize the RA document or the new IRIS file because of internal and external disagreement over some of the data analysis in the RA document. EPA has since initiated a consultation with the National Academy of Science to review parts of the RA document. When the review is complete, EPA will finalize the RA document and the IRIS file. But this will take some time. Meanwhile, NCEA has been reluctant to support the proposed new cancer slope factor or recommend using it as the provisional value. Therefore, as with PCE, the CalEPA values are acceptable as the most recent data from an approved tertiary source of reference data according to the Cook memo. -1 -1 

### The CalEPA provisional toxicity values are: CSF O 

### = 0.013 (mg/kg-day) ; CSF I 

### = 0.007 (mg/kg-day) ; 3 3 3 I 

### Chronic Inhalation REL = 600 (mg/m ) thus, RfC = 0.600 (mg/m ), RfD is 0.600 times 20 (m /day) divided by 70 kg = 0.17 (mg/kg-day). The only existing RfD O 

### is 0.006 (mg/kg-day) originally provided by NCEA. The 2001 document with the new CSF also includes a new RfD O
